REQUEST FOR ADDITIONAL INFORMATION RELATED TO GENERIC LETTER 97-04, PEACH BOTTOM ATOMIC POWER STATION (PBAPS), UNITS 2 AND 3
' (TAC NOS. MA0025 AND MA0026).
Dear Mr. Edwards:
..The NRC staff issued Generic Letter (GL) 97-04, Assurance of Sufficient Net Positive Suction
- Head for Emergency Core Cooling and Containment Heat Removal Pumps," on October 7,1997.
In that GL, the staff requested that the licensees provide information necessary to confirm the adequacy of the net positive suction head (NPSH) available for emergency core cooling and containment heat removal pumps. By letter dated December 30,1997, The PECO Energy Company (the licensee) submitted its 90-day response to GL 97-04.
The NRC staff has reviewed the response and is concemed that the Peach Bottom Atomic Power Station (PBAPS)l Units 2 and 3, may not be within its licensing basis because it appears that the containment overpressure needed to assure adequate NPSH is greater than the ovemressure previously approved by the NRC staff. Please provide a response within 30 days from the date of the receipt of this letter, discussing how your response to GL 97-04 related to containment overpressure compares with your current licensing basis, if it is determined that
' PBAPS, Units 2 and 3, is outside of its licensing basis, the staff expects that the licensee will
- take prompt action to modify PBAPS, Units 2 and 3, licensing basis as appropriate in accordance with the regulations, or otherwise restore the facility to a condition consistent with the licensing
.{
- basis. Should you have any questions, please contact me at 301-415-1476.
I Sincerely,
